Definitions

  • the present invention relates to a system and method for verifying the integrity of a train.
  • the object of the invention is therefore to provide a system and a method for verifying the integrity of a train which are of reduced cost while providing the necessary security to meet railway standards.
  • Another object is a computer program product including program code instructions for implementing the steps of the method when said program is running on a computer.
  • a train 1 runs on a railway track 2 comprising a detection circuit.
  • this circuit is formed of a short track circuit 3.
  • track circuit refers to the electrical circuit of a perfectly delimited portion of a known length of track that is electrically isolated and which makes it possible to control the occupation of sections of track or needles.
  • a short track circuit corresponds to a portion of track whose length is reduced to the minimum while ensuring that, during the passage of a train, at least one axle of this train is permanently on the portion of track.
  • the short circuit circuit and the corresponding channel portion will be indifferently called short circuit circuit.
  • the short track circuit 3 comprises means 4 for detecting the presence of a train thereon.
  • Train 1 has an odometer 5.
  • This odometer 5 indicates the distance traveled by the train with a relative uncertainty known to the manufacturer. As a general rule, odometers fitted on trains have a relative uncertainty of ⁇ 2%.
  • the short track circuit 3 and the train 1 also comprise communication means 6, 7 enabling them to exchange information.
  • These communication means 6, 7 are radio communication means, or power-line communication means on the rails or any other suitable system.
  • These communication means 6, 7 are adapted to allow the synchronization between the events of the beginning of presence of the train on the short track circuit 3 and the release of the train 1 on the short track circuit 3 and the odometer 5, so the odometer 5 determines the odometric values corresponding to these two events.
  • the train comprises means 8 for storing the odometric values determined by the odometer 5.
  • the train also comprises means 9 for calculating the distance traveled by the train between the moment of beginning of occupation and the instant of release.
  • Calculation means 10 for determining the minimum length of the train are connected to the means 9 for calculating the distance.
  • the train also comprises means 11 integrity information to prevent the driver for example.
  • the means 8, 9 and 10 are integrated in a computer embedded in the train.
  • FIG. 2 illustrates the moment when the train 1 begins to occupy the short track circuit 3, that is to say that its first axle enters the short track circuit 3.
  • the odometer 5 indicates an odometric reference D 1 .
  • the short track circuit 3 has a length I cv , the train a length I t and the last car a length I w .
  • FIG. 3 illustrates the moment when the train 1 releases the short track circuit 3.
  • the odometer 5 indicates an odometric reference D 2 .
  • the axles are supposed to be positioned at the front and rear limits of the train. It is easily understood that the length of the short track circuit 3 has a length greater than the maximum distance between two axles so that at least one axle is inside the short track circuit for the duration of the passage. of the train.
  • the length I CV of the short track circuit is perfectly known and is stored in the calculation means of the train.
  • the communication means 6 of the short channel circuit 3 have transmitted to the train the value I CV in a prior initialization step.
  • the odometric values D 1 and D 2 comprise uncertainties related to the odometer 5, to the accuracy of the synchronization between the means 4 for detecting the short track circuit and the odometer 5, and to the delays related to the delays. release or occupation of the tracks.
  • the calculation means determine an interval of distances (D min , D max ) such that the probability that the distance traveled by the train is not in this interval is less than a probability compatible with the standards of railway safety, for example 10 -12 .
  • the measured length of the train therefore varies, according to equation (1), between D min -I cv and D max -I cv with D min corresponding to the minimum value of D 2 -D 1 and D max to the value maximum of it.
  • D min D 2min - D 1max
  • D max D 2max - D 1min .
  • D min can be equal to D 2min -D 1min and D max to D 2max -D 1max .
  • the calculation means 10 compare the measured length with the predetermined length l t minus the length of the wagon I w .
  • the minimum measured length is less than the predetermined length of the train minus the length of a wagon, then the train is considered not to be intact.
  • the system thus described therefore advantageously makes it possible to detect the integrity of a train at a reduced cost since the short track circuits are already installed on the tracks to detect the presence or the absence of a train and the new trains currently put in place. in service include onboard odometers.
  • a specially programmed on-board computer connected to the odometer 5 and the control means 4 of the short channel circuit then makes it possible to perform the calculations and to transmit the integrity information.
  • FIG. 5 uses two short track circuits 3, 50 remote by a length I 12 to delimit the detection circuit, such that this length I 12 is less than the length of the train.
  • the moments of reading of the odometric references then correspond to the moment when the train 1 enters the second short track circuit 50 and at the instant when it releases the first short track circuit 3, which is therefore upstream. the second short track circuit 50 relative to the train running.
  • the calculated length of the train is equal to the sum between the minimum distance traveled and the distance between these two short track circuits, and is therefore independent of the length of the short track circuits.
  • This variant embodiment makes it possible, by lengthening the measured distance traveled, to reduce the uncertainty of the measurement and therefore to increase the accuracy of the detection system.
  • the system comprises means 60 for validating the measurement.
  • These validation means 60 use the maximum distance traveled D max .
  • the measured length of the train is in the range (D min -I cv , D max -I cv ).
  • the validation means 60 conclude that the measurement is invalid and trigger an alarm.
  • This variant is advantageously usable during the formation of the convoy at the marshalling yard, in addition to a conventional car counting system to validate the integrity control system.
  • the short channel circuits are adapted to transmit the occupancy / release detection information accompanied by the time at which this occupancy / release occurred.
  • the accuracy of the system is increased by reducing the uncertainties of the odometric values D1 and D2 related to the delay of transmission of the signal.
  • the system and method thus described thus advantageously make it possible to check the integrity of the trains at a reduced cost by the use of pre-existing elements on railway networks and traction machines.
  • the length I cv of the track circuit used in equation (1) of the embodiment of FIG. 1 and the distance between the two short track circuits -I 12 used in equation (2 ) correspond to a generic term called algebraic length shift of the detection circuit
  • the detection circuit can be described as a segment of lane oriented in the direction of travel of the train.
  • the algebraic offset of the detection circuit length reflects a predetermined algebraic bias involved in the calculation of the length of the train.
  • step f) In the case where the result of the test performed in step f) is positive, the train is then suspected of not being integrity and step e) is not performed.
